Lee Spring Ltd is continuing to expand its extensive portfolio of 23,000+ standard compression springs that are available ex-stock for rapid delivery. In addition, the company manufactures custom springs to suit manufacturing across all areas of industry as part of a prototyping-to-production programme.
The Lee Spring compression range includes Bantam mini springs from 0.64mm outside diameter in cobalt-nickel alloy. Bantam springs find uses in medical devices, precision instruments, aerospace and many other control/process/security devices.
Other specialist compression designs include AISI 316 grade stainless steel Lite Pressure springs for use where a low-pressure, large-diameter spring is required to spread force over a relatively large area - for example, in relief/check valves, electrical contacts, toys and syringes.
Hefty die springs, with their high-performing round wire section, offer a like-for-like performance at typically one-third to one-half the cost of traditional rectangular wire die springs. They are extensively used in non-die applications where their price/performance ratio enables users to also benefit from their high quality and reliability.
In a similar vein the range of LeeP plastic composite compression springs combine the strength of metal with the special attributes of high-performance engineered thermoplastics. This approach maximises spring rates and cycle life with high strength-to-weight ratios, along with high resistance to corrosion and chemicals. In addition, of course, they are non-magnetic, non-conducting and non-contaminating, as well as being recyclable and RoHS/REACH compliant.
Since the specification of compression springs is often a matter of physical testing - and for the convenience of one-off frequent users in development or service sectors - Lee Spring also has available a set of spring kits containing a selection of different sizes of compression springs in music wire or stainless steel.
